Romelu Lukaku's incredible body transformation has been praised by former Chelsea assistant Jody Morris and fans after returning to the club in 'great condition'.
The Belgian striker re-signed for Chelsea this summer for a sizeable £98million fee, and has already got back to work in training with his new team-mates ahead of a potential second club debut against Arsenal on Sunday.
And ex-Blues boss Frank Lampard's assistant manager Morris took to Twitter to hail Lukaku's physical condition.
He said: 'Not sure if it's just me but Lukaku looks in great condition by the way (muscle emoji).. Not sure I remember him looking as lean as this when previously in the Prem??'
The 28-year-old was playing at a weight of more than 100kg while at Old Trafford, a cause for concern for Inter Milan manager Antonio Conte when he moved to the San Siro.
Conte arranged an appointment with specialist Matteo Pincella, who ran the rule over him - including studying decomposition of his body waste, according to ESPN - and discovered a digestive problem which was hindering Lukaku.
A crack new diet with fried food and potatoes cut and based on raw vegetables, fish, sweet potatoes and pasta saw him lose half a stone in just 12 days and success followed on the pitch, with 64 goals in 95 appearances in two seasons at Inter.
Lukaku told Inter's official podcast: 'When I joined Inter we did an analysis of my body and a lot has changed. I eat a lot of salad and fish, which has a great effect on me. I take carnitine, it makes me feel good, and I take vitamins.
'I eat salad for lunch, a lot of chicken breast, shirataki noodles. Since following this lifestyle I feel better on the pitch, more responsive and faster. I love sweet potatoes and black rice, I don't eat pasta.
'I have reached another level, physically and mentally. The day before the game I can go overboard with carbohydrates. After most matches I eat two packs of gnocchi. They get into my circulation quickly, they help me a lot. I drink and eat at the stadium, in our canteen, or I take my food home, then recover with lots of ice.'
A slimmer, more mobile Lukaku, in the goalscoring form of his life, could be unleashed against the Gunners this weekend for Thomas Tuchel's side.
